POLYMER 80 AR15 80% LOWER RECEIVER KIT VERSION 3 RL556V3 – BLACK


The RL556v3™ features Polymer80’s proprietary polymer composite, a solid core design, flared magwell, and beefier mil-spec buffer tube housing. The pistol grip area features a unique threadless design specific to Polymer80 rifle lowers.

The kit includes:

  • 80% Polymer AR15 Lower Receiver (Mil-spec)
  • Polymer Jig
  • Trigger Hole Drill Guide
  • Drill Bits and End Mill

Please note: An end mill bit is no longer included in this kit as it was deemed unnecessary by the manufacturer, Polymer80.

Once you receive your kit, you can get to building right away. Completing your 80% Frame with the included Jig takes less than one hour with the provided drill bits and end mill bit. All you’ll need is a drill and router or hand files!

The ATF has clarified that private citizens are legally allowed to build this type of handgun – or any other non-restricted firearm – at home, with no paperwork necessary, with no intent to sell. That means you can order your frames with no additional paperwork!

To download the ATF Determination letter that deems that an 80% frame/receiver is NOT a Firearm in it’s unfinished state, please click HERE. (The determination letter is for both the .308 rifle lower and the PF940)

As always we urge you to research your own state and local laws regarding finishing an 80% Receiver and ownership of the 80% frame. There are some state and/or local laws that may prohibit purchasing this item.
